Still banging my head on a wall here.
EEPROM is enabled in Marlin but the offset is not making any difference to my prints. The head is just dragging through the plastic. As a test I even set the head offset to M555 Z4 as i knew this should be too high, the program just ignores it though.
M501to reads the current EEPROM configuration. Look for a line such as
M206 X0.00 Y0.00 Z-1.80 ZProbe-1.95That "ZProbe" value is what you need to change. Set it with
M555 Z-1.5 ; or whatever you want the new offset to be. M500 ; immediately store the new offset

Hi,
I'm not entirely sure about the problem, but I think I've been fighting the very same problem today. It seems that Z_PROBE_OFFSET_FROM_EXTRUDER_DELTA_X might be the source of this behaviour. As far as I can determine, it tells the firmware how much further down the probing is pushing the outer side of the bed before activating the endstop, because of the the way the bed is better supported on the inner side. If your contruction is more solid than assumed (the default is .5 mm), the far end is not pushed that far down in reality, and therefore the printer thinks it needs to compensate more than it does, and ends up printing too high on that side.
I tried setting Z_PROBE_OFFSET_FROM_EXTRUDER_DELTA_X to zero and went from having the floating filament to having the first layer just a bit too flat on the bed, while the side closest to the X endstop was the same in both instances. I guess that means tomorrow I'll have to try with a value of .1 to .2 and that'll be it.
